Re: [jQuery] Re: jQuery 1.4 change event problem

[Steven Yang]

sorry not too sure what you have concluded here.
so do you mean after you do the select by code, the problem is solved? or
still occurs?

and is this a problem that jQuery may be responsible to handle or are we
suppose to handle ourselves?
i was already forced to downgrade back to 1.3.2 because of this, because we
do a lot of submit onchange.

thanks

[jQuery] jQuery 1.4 change event problem

[Steven Yang]

Hi all

I apologize if this problem has been post or report.

I have a problem using jQuery 1.4 when i use
$("#mySelect").change(function(){...my logic...})

This problem only occurs in IE. 6-8 all have the same problem and jQuery
1.3.2 does not have this problem.

This problem occurs when I bind a "change" event on a select and when the
page is loaded the selected option is not the first one.
What will happen is when I click on the select and not even have a chance to
choose my option, the "change" event is fired. But after the first change,
things works normally.

i made a simple sample here:
http://jsbin.com/apufa/ 

you will notice when you click on the select the alert will fire, but it
should only be fired when i actually change the option.

is this a bug?

Thanks

Jon what version of blockUI are you using? I think i just ran into similar
problem yesterday when i upgraded jQuery to 1.4 and blockUI stopped working.
but i solved it by upgrading blockUI to the newest version then everything
worked again. i think the newest version was updated some time in Jan 2010

you are not able to parse the xml at all right?
i believe for IE you have to make sure you server returns the correct

hope this help

[jQuery] Re: Browser sniffing - the correct way?

[Steven Yang]

AFAIK $.broswer is not the way to go in latest jQuery is simply because
browser sniffing is not recommended and not the jQuery way of getting things
work cross all browsers.and not that because $.browser has problem itself

it really depend on why you need to know the different browsers. jQuery
recommends "feature detection" in contrast to "browser sniffing"

all i can think of the only reason to use browser sniffing is to solve the
IE6  problem.
of course i maybe wrong

how about just try loading the jquery-1.3.2.js first and see if you get the

and if that works then try loading one after another and see which one is
having error.

[jQuery] Re: jquery resistance at work - advice? OR mvc in js, needed?

[Steven Yang]

Hi
I am a java guy myself.
from what i know some famous java framework has adopted dojo as their
default support for their client side tech. And the Struts2 used to include
dojo as their native support, now as a plugin i think.

I an understand why your java guy is always mvc this mvc that. Its almost
what we talk about when it comes to design.

I think it really depends on why you need MVC on your javascript side.
If your client side need to be run in different environment. for example,
browser (online, offline with gears), or in AIR with the same code. Then MVC
is probably what you have to consider.
I am not too familiar with dojo, only used it for a while when i wasnt good
at javascript, but hated the complicated API.
I personally really like ExtJS's way of doing things, even though i use
jQuery now.^^

I think the main reason(as far as i can think of) for doing MVC is when you
are in a situation where your client side(javascript) does not know where
your data is coming from and the format will change. ie. JSON, XML, or even
plain text.

here is just my opinion
correct my if i am wrong on anything

[jQuery] Re: problem xml with jquery IE 8

[Steven Yang]

sorry i may be wrongbut until someone has a real solution
here's something you can try

1. make your dataType -->dataType: "xml"

2. not sure if the problem still exists in IE8, but IE seems to have a
problem determining an incoming data as XML, so make sure your server
returns a header that tells the browser that the content-type is XML.

[jQuery] Re: $.each cannot iterator my array

[Steven Yang]

you are doing a very weird thing to an array
I guess jQuery detects that myArray is a reall Array.
Then it iterate over it by using the "length" attribute. However you didnt
actually put anything into the Array "myArray" therefore, you dont get
anything.

[jQuery] Re: can't return value after $.ajax call

[Steven Yang]

by using "var bool = true;"you made "bool" local to your callback and not to
your "checkIfUsername"
so "checkIfUsername" does not have a reference of bool you have to make bool
local to checkIfUsername so you first declare "var bool" in checkIfUsername,
then allow your callback to assign it a value.

[jQuery] Re: can't return value after $.ajax call

[Steven Yang]

if thats the case try
function checkIfUsername(o)
{
  var bool;
   $.ajax({
   type: "POST",
   url: ""+CI_ROOT+"index.php/admin/check_if_username",
   data: ({username: username.val()}),
   async: false,
   dataType: "json",
   success: function(data){
   if(data.bool == true){
   o.addClass('ui-state-error');
   updateTips("Your username must be unique");
   //return false;
   bool = false;
   }
   else{
   //return true;
   bool = true;
   }
   }
   });
  return bool;
}

i am not very familiar with the case that async:false
but from what you described, this should work

[jQuery] Re: can't return value after $.ajax call

[Steven Yang]

aside from the fact that checkIfUsername does not have a return
ajax function is not going to waitwhen you finished calling $.ajax your
function has already ended(returned)
then when server responded your returnUsernameBool will be called but thats
already too late for your alert(bValid)

thinking as $.ajax is creating another thread and your callback is run in it
might help (eventhough javascript is single threaded)

If not mistaken, there is a sorting plugin somewhere or even in jQuery core.
